Depends on where you go. College coaches don't want to (and many wont) spend time teach incoming freshman how to "cheer." Thats why a lot of colleges like it when girls have a high school cheer background. If you've never cheered a ball game you don't have the crowd leading skills that you gain from that experience. Even at highly competitive programs, 85% or more of college cheer revolves around games, crowd leading, public appearances, etc, not competitions. This isn't saying that a team won't take you without high school cheer experience, because most will. If you don't do it then get with someone who has cheered in college and have them work with you on how to crowd lead and be a game day cheerleader.
My girls high school team is not good and its the coach that makes it that way. When girls ask me what to do I advise them to do allstars. They have game experience from middle school, which while that doesn't really count in a college coaches eye, I think its smarter for them to get in a good allstar program and keep improving as opposed to going to the high school they're zoned for that has an unqualified coach that is known for making girls worse then when they came in. I think you need to look at the high school team and determine if it will help you or hurt you to be a part of it.
